Abstract: A pick-up style utility vehicle according to the present invention has a front seat, a rear seat, a cargo bed expandable in a front direction, and a screen shield arranged at a front end of the cargo bed. The cargo bed has at least a stationary bottom plate, right and left stationary side panels, a front panel, expandable side panels, and an expandable bottom plate and can be changed between an expanded state in which the cargo bed is expanded in a front direction to a rear portion riding space and a non-expanded state not occupying the space. Each of the expandable side panels and the screen shield are supported by a vehicle body configuring portion so as to be integrally shifted between an expanded position and a non-expanded position.

Abstract: A throttle valve controller configured to control opening and closing of a throttle valve disposed in an air-intake passage of a throttle body coupled to an engine, including an input member that is rotatable in association with a rider's hand operation, a power transmission device with an input part thereof coupled to the input member, an output member that is coupled to an output part of the power transmission device and causes the throttle valve to rotate in association therewith, an actuator configured to drive the power transmission device to cause the output member to rotate relative to the input member to change a rotational ratio of the output member to the input member independently of the hand operation, and a movable stopper configured to change and restrict a rotational range of the input member in a closing direction of the throttle valve.

Abstract: Provided is a hull shape of a personal watercraft which can enhance speed performance, and still more, can also reduce rolling of a body. A bulging face 12 is formed on an outside part of a rear portion of a hull bottom 20 having a substantially V-shaped cross section and protrudes downward from an outside front face 20a positioned in front of the outside part. The bulging face 12 includes a fore part 13 inclined downward in the rearward direction, and a rear part 14 positioned above a virtual face A extended rearwardly from the fore part 13.

Abstract: A bottom structure of a personal watercraft enhances the running performance of a personal watercraft. A concavo-convex face (21) having very small concave or convex portions for drawing air from an outside of a watercraft is formed on a water contact face (S) in a bottom surface (20) of the personal watercraft during planing. The air is drawn by the concavo-convex face (21), thereby separating a water flow from the bottom surface (20). Consequently, frictional resistance to the water in the bottom surface (20) can be reduced.

Abstract: In a liquid level detecting device for fuel or oil in a small size boat, a liquid level detecting switch turned on and off in accordance with a vertical movement of a float provided in a tank and a liquid level warning device are connected in series to a power supply circuit from a generator of an engine.

Abstract: This disclosure relates to a water craft or boat including an engine room for an engine. The room is closed except for an opening through which intake air moves into the room, whereby the engine is supplied with intake combustion air. An exhaust line also extends between the engine and the outside of the room. Cooling means is provided in the room to collect coolant discharged from the engine and to inject it into the exhaust line in the room, whereby the coolant is discharged out of the room together with exhaust gas from the engine. Fuse means is provided in the exhaust line in the room downstream from the location where the coolant is injected. The fuse means is heat fusible to thereby form an opening when the gas in the exhaust line exceeds a predetermined temperature, whereby exhaust gas enters the room through the opening. The exhaust gas is drawn into the engine intake, causing the engine to fail to operate or to falter.

Abstract: A fuel tank comprising a wall forming a main container for fuel, and a lateral extension from said main container. The extension is located adjacent the bottom of the main container, and the extension has at least one tranparent or translucent wall so that any water accumulated at the bottom of the tank and in the extension may be visibly detected.

Abstract: An apparatus for detecting the oil level in an oil tank of a marine craft. The fuel inlet of a fuel tank which is disposed within a craft body is provided outside of the craft body in an exposed state. The oil tank is arranged adjacently to the fuel tank, and an oil level detecting means for this oil tank is arranged adjacently to the fuel inlet such as to allow the oil level to be directly observed from the outside of the craft body.

Abstract: In a semi-axial flow pump used in a small-sized boat which is intended to travel in shallow water, a truncated-conical liner of wear-resistant material is force fitted into the inner surface of a passage portion within which an impeller is mounted. The liner has cylindrical portions at its both ends, which are effective to forcibly fit the liner into the pipe passage portion.

Abstract: This disclosure relates to an air intake arrangement for a small boat including a hull, wherein the front end of a handle pole of the boat is supported pivotably on a horizontal shaft on the upper deck of the hull at a position which is on the longitudinal center line of the hull, and a handle lever to be held by an operator is attached to the rear end of the handle pole. An air intake port for taking fresh air into the engine compartment in the interior of the hull is provided on substantially the center line at a position corresponding to the lower side of the handle pole on the deck, and a lead-in opening for taking the air from the front of the boat and leading it into the air intake port is formed in the handle pole.
